Product details
MAX3232 IC is extensively used for serial communication in between Microcontroller and a computer for changing the TTL/CMOS logic levels to RS232. So, if we want to interface any microcontroller with the Computer, first we have to convert the logic of TTL /CMOS to RS232. Alternate names of this IC are; RS232 to TTL Converter IC, MAX3232IDBRE4, AX3232CAE, MAX232CSE, MAX3232 SMD IC, MAX3232 IC, Surface Mount Device RS-232 Transceivers IC, SMD IC, RS-232 Transceivers SMD & SMD IC. This article discusses an overview of a MAX3232 IC, pin configuration, specifications, and its applications. What is MAX3232 IC? MAX3232 IC is a converter IC, used to convert RD232 to TTL. This IC includes line drivers-2, line receivers-2 & a circuit for dual charge-pump including ESD protection from terminal to terminal with 15 kV. The requirements of TIA/EIA-232-F can be attained by this IC to provide an interface in between the serial-port connector & an asynchronous communication controller. MAX3232 IC Transceivers like MAX3222 & MAX3232 use fewer dropout transmitter output phases and also dual charge pumps for achieving the right RS232 performance once powered through the supply like 3V-5.5V. The supply voltage of max3232 is 5volts or 3.3 volts, which uses 0.3mA of power which is connected externally through 4 0.1uF capacitors. Pin Configuration: The pin configuration of MAX3232 IC includes 16- pins where each pin and its functionality is shown below: MAX3232 IC Pin Configuration Pin1 (C1+): This pin is the positive terminal of capacitor ‘C1’. Pin2 (V+): Positive charge pump o/p for storage capacitor only. Pin3 (C1-): This pin is a negative terminal of capacitor ‘C1’. Pin4 (C2+): This is a positive terminal of the ‘C2’ capacitor. Pin5 (C2-): This is a negative terminal of the ‘C2’ capacitor. Pin6 (V-): Negative charge pump o/p for storage capacitor only. Pin7 (DOUT2): The output of RS232 line data. Pin8 (RIN2): The input of RS232 line data. Pin9 (ROUT2): Logic data o/p to UART. Pin10 (DIN2): Logic data i/p from UART). Pin11 (DIN1): Logic data i/p from UART. Pin12 (ROUT1): Logic data o/p to UART). Pin13 (RIN1): The input of RS232 line data from the remote RS232 system. Pin14 (DOUT1): The output of RS232 line data to remote RS232 system. Pin15 (Ground): Ground pin. Pin16 (Vcc): Voltage supply pin. Features & Specifications: The features and specifications of MAX3232 IC include t...
